which, while susceptible of more general use,

is particularly well adapted for the loading of ore cars in the tunnels of mines and like situations. The invention consists in the features of novelty hereinafter dwcribed, illustrated in the accompanying drawings and particularly pointed out in the claims at the end of this specification.

Figure 1 is a View in side elevation of an apparatus embodying my invention. Fig.2 is a plan view. Fig. 3 is a v ew partly in plan and partly in section upon an enlarged scale. Fig. 4 is a. View in vertical section on line 4 4 of Fig. 3. Fig. 5 is a view in central longitudinal vertical section showing the shovel in elevated position. Fig. 6 is a detail front view of the shovel and the upper portion of the shovel carrying arm and ad'acent arts.

In the prel erred form of my invention illustrated in the accompanying drawings, the apparatus comprises a platform suitably mounted upon wheels 21 adapted to travel upon the rails 22 of the truck leading into the tunnel and to the point at which the loading of the cars is to be effected. Upon the truck or platform 20 is pivotally mounted the body portion of the apparatus, this pivotal mounting of the body portion being preferably effected by a king pin 25 passing through center bearing sleeves 26 and 26 bolted respectively to the floor 27 of the body portion and to the platform 20 (see Figs. 4 and 5). As shown, anti-friction rollers 28 held in suitably formed brackets 28 are secured to the under side of the floor 27 of the apparatus, to enable the body portion to be freely swung as a turn- 25 as a center. In

receive a pin 29' ti at passes through a. 11016.

formed in the floor 27 of the body portion.

The body portion of the .ap aratus may be formed of a lower metal p ate or floor 27 having upturned flan es at its sides, to which flanges are suitab y secured vertical side plates 30. Preferably, these side plates are l' aced at their forward ends by the standards 31 that may be of angle bar, and additional braces may be used if desired. Between the upper ends of the side plates extends a cross bar 35 (that is shown as a channel bar) on which is mounted a short shaft 36 car ing a pulley 37,the function of which wil presentl appear.

' Upon the fioor 27 o the body pwion of the apparatus is mounted a pair of rails 40 that will be arranged at a distance apart corresponding to the age or distance between the rails 22. referably, the front ends of the rails 40 will be provided with stop blocks 41, and to the rear ends of the rails 40 ergpivotally connected, as at 42, extensions 43 adapted to turn down onto and coincide with lthe rails 22. The ivotal ,ends of the extensions 43 are pre erably provided with suitable spuds to prevent the backward movement of the apparatus when in operation, but as these spuds form no part of my invention, I have not deemed it necessary to illustrate them in the accompanying drawings:

1 pen the body portion of the apparatus are suitably mounted the compressed all cylinders to the rear ends of: which are connected the pipes 51 and 52 by which compressed air from a suitable source of supply will be admitted to the cylinder??? Ill till The pipe 61 may be led to the side of the apparatus as shown and will be provided with a controlling valve whereby the admissiorr aml exhaust of compressed air to and from the cylinders can be convenientl y effected. Within the rylinders 50 are mount.- ed the pistons 54 from whirh extend the piston rods 55, the outer ontls of these rods being pivotally rennet-led, as at 56, to the rear end of the shovel arm till. This shovel arm (it) is preferably formed of side bars 61 suitably brueed by the bars 13,2 and 625, the outer ends of these side bays being connected by a cross head (if) itlnitearries the shovel or scoop 7U. 'lhishdvel or seoop 70 is preferably of the shape shown and its back plate is hinged, as at 69, to the rross head 65 of the shovel arm. .10 this rross head 65 is rigidly seeured a bar 72 the l'orwardly projerting portion of whieh is adapted to extend beneath the. bottom of theshovel or scoop 70. To the rear portion of the shovel or seoop Tl) is serured a dum ing arm 73 that extendsrearwardly and up wardly, as clearly shown in Fig. and is adapted to contact with the rross bar wheroon the pulley 37 is mounted.

To the eross head ()5 ol' the shovel arm 60 is attached one end of a rable 8H that leads rearwardly up over the pulley EST and downwi rdl to the winding, drum SI of a hoist that is mounted upon the forwardly extending portion of the Hour .3? ol' the ap paratus. Any suitable type of hoist may be used for operating the till)lt' so and l have shown one common 'l'orm of mine lloisl that ist'lperated by (()!ll])l't. fit'll air. A hand lever H5, whereby is eli'erted the admission and exhaust oi' eomprossed air to the t-' \'l* ilulers of the hoist, is arranged in ronvenient position to be operated by the attendant standing at one side of the apparatus.

From the foregoing description. the oper ation. of my improved apparatus will be seen to be as follows: Assuming that an oro (.'ar 90 (shown b y.dotted lines in Fig. 5)

is pt bed from the main tiaokulltu the. rail N that the shovel or seoop is in the low'l'tl or retrarted position shown Irv full lines in Fig. l the operator will admit air to the cylinders 50. rausing the piston rods of these rylinders to more outward tlushovel arm (as shown by dotted lines) and force it into the pile ol" ore in front. of it. When the shovel is loaded. the rontrollin; valve for the air rylinders 5!) will be turned to exhaust position. and by the operation of thehand lever 85 air will henuhnitted to the rylinder of the hoist so as to ranse the windint drum 81 to wind up the table 80. As the cable 80 is wound upon the winding drum Hi. it will first draw inward the piston rods to the retrarted position shown in Fig. l of the drawings, after which the continued winding of the cable so will lift the shovel arm and shovel (as shown by dotted lines Fig. 1) until the dumping arm 73 attaelu-d to the bark end of the .\llU\'t'l rontarts with the cross bar 35, thereby musing the shovel to tip about its pivot points (it) and dis-(barge its load into the rar 911. lly varying the peed of the hoisting cable. the load of the shovel may be dumped at any desired point within the rarl and thus the load in the ear may be uniformly distrilulted.

luasrnurh as minin; tunnels are usually of small area (ordinarily about F6 Feet in diameter). it is desirable when the apparatus is employed for thi.-- purpose. that the shovel arm shall la-romparatively short so that as it is swung: upward to dump the shovel load into the ear the v hovel will not rontart with the top ol the tunnel. and by attarhin; the shovel arm to the outer ends of the piston rods. the initial retrartion of the piston rods allows the shovel arm to be drawn inward before the shoiul is lifted to dump its load. When the liHYtl is to take the ore from either side of the pile at the end ot' the tunnel. the body portion of the apparatus ran be swine. laterally upon the platform and by nirans of the pin 29 can be held in the desired position. when the ear on has rrveiual its load. the body portion of lhe apparatus will be br ii'l t to normal lmsllltill so that the ails to will aline with the rails 2'2. aiter which the loaded rar 9H may be drawn away.
